To github.com:memoriesadrift/solana-research-poc.git dfa87c9..f242128 main -> main A simple script that creates two accounts on the Solana devnet, airdrops some funds into them and then transfers funds from one account to the other.
Install dependenciess, then run, simple.

- Send Transaction
- Create Staking Account
- Delegate Stake
Proof of History - Trustless establishment of a concept of time Uses a verifiable delay function, VDF This allows transactions to happen very quickly, a new block is created every ~400ms
- Smart contracts are written in Rust or C (or C++, but I haven't found any tutorials aimed explicitly at C++), with Rust generally being preferred.
- The JS library, solana-web3-js is not documented very well and mostly contains just an overview of functions that are available and the parameters they take.
- It seems the docs are being reworked now, though, so we shall see what comes of it.
- SOL tokens in your wallet must first be moved into a stake account. You can create as many stake accounts as you like, and deposit as much or as little SOL into each stake account as you want. Each new stake account has a unique address, and a single wallet can manage or “authorize” many different stake accounts. https://docs.solana.com/staking/stake-accounts
- Certain types of accounts may have one or more signing authorities associated with a given account. Staking accounts have the stake authority and the withdraw authority which allows that account to delegate tokens and the tokens to be withdrawn and for a new instance of each of these authorties to be set!
- It is possible to stake locked tokens (such as tokens received as rewards from Solana grants)
- Process of staking: https://solana.com/staking#removetokensstake
- Rewards are issued once per Epoch
- As the number of nodes on Mainnet Beta continues to grow, the Solana Foundation is committed to continuing to delegate 100M SOL to be split evenly among qualified validators. In order to increase growth to up to 500 individual nodes, which will help increase the security of the network, qualified validators will receive Foundation delegations of up to 200,000 SOL.
- Fundamentally, our goal for slashing is to slash 100% in cases where the node is maliciously trying to violate safety rules and 0% during routine operation. How we aim to achieve that is to first implement slashing proofs without any automatic slashing whatsoever.
- Right now, for regular consensus, after a safety violation, the network will halt. We can analyze the data and figure out who was responsible and propose that the stake should be slashed after restart.
- A similar approach will be used with an optimistic conf. An optimistic conf safety violation is easily observable, but under normal circumstances, an optimistic confirmation safety violation may not halt the network. Once the violation has been observed, the validators will freeze the affected stake in the next epoch and will decide on the next upgrade if the violation requires slashing. In the long term, transactions should be able to recover a portion of the slashing collateral if the optimistic safety violation is proven. In that scenario, each block is effectively insured by the network.

- 100% of the inflationary issuances are proposed to be delivered to delegated stake accounts and validators.
- Initial Inflation Rate: 8 % Dis-inflation Rate: −15% Long-term Inflation Rate: 1.5% https://solana.com/staking#inflationrate
- Create a Staking Account. Can be done via Solana CLI or via code in JS / Rust -> An on-chain transaction.
- Send funds to Staking Account.
- Delegate your Staking Account to a validator.
If you transfer tokens into a stake account that is already delegated, these new tokens will not automatically be delegated. In order to get these new tokens also delegated and earning rewards, you would need to un-delegate the entire account, then re-delegate the same account. As un-delegating and re-delegating can take several days to take effect, your original stake would not be earning rewards during this transition period Therefore, we recommend only transferring SOL into a stake account when it is first created or otherwise not delegated.
